every afternoon i come home wanting to play some AoC, I been suffering really hard for so long now because of this maintenance at specifically 09:55 GMT. Usually this forces me to have dinner, when instead i just want to play AoC. Changing the time back slightly would definitely be great.

Our chosen time window is based on the player activity on Voobly, which is the lowest at 10 AM GMT with approximately 900 players. Three or even four hours sooner would mean, that 1,5k - 2k players would be affected, three or four hours later would affect > 1,5k players. This cannot be a serious suggestion. We also talk about a time window of approximately 10 - 20 minutes.

It could be scheduled at 9 AM GMT instead of 10 AM GMT, but I don't see, how this would solve your problem.
